An ECFanGrid consists of several EC fans operated in parallel in a kind of fan wall. The volume flow is multiplied proportionally to the number of fans, while the pressure conditions remain constant. The EC fans used are not only highly efficient, but as a perfectly matched unit (electronics, motor & impeller) they also enable simple plug & play solutions for almost any ventilation requirement.

In addition, several controllable fans can be adapted much better to the actual air performance required, which increases efficiency at every operating point.

The ECFanGrid Retrofit System is particularly suitable for replacing old, inefficient belt-driven fans in ventilation units. It does not matter which brand is in use. The Retrofit System is flexible and always suitable!

All components, from the fans to the switch cabinet and the adaptive sheet metal parts, come from our own production and are part of every ECFanGrid Retrofit System from Rosenberg.
